Question
Assume that we want to construct a confidence interval. Do one of the following, as appropriate: - Find the critical value \( t_{\alpha/2} \) - Find the critical value \( z_{\alpha/2} \) - State that neither the normal distribution nor the t distribution applies. The confidence level is 99%, \(\sigma\) is not known, and the histogram of 59 player salaries (in thousands of dollars) of football players on a team is as shown. **Histogram Description:** - The horizontal axis represents salary (in thousands of dollars). - The vertical axis represents frequency. - There is a bar between $0 and $2000 with a frequency of around 35. - There is a bar between $2000 and $4000 with a frequency of around 15. - Smaller bars are present between $4000 and $6000, $6000 and $8000, $8000 and $10000, and $10000 and $12000 with lower frequencies. - There is a single bar between $20000 and $22000 with a frequency of 1, indicating an outlier.
